Frequently Asked questions

1.What are the benefits of cylindrical worm gera set over ordinary worm gear drive?
The unique worm profiles faciliate the fomation of oil film at the contact surface of the gear teeth.The lubricating oil is able to maintain a low temperature and has excellent anti-scuffing capacity.
2.What is the ideal working temperature for a worm gear speed reducer?
What is the temperature when operating at full load?
Hongwei worm gear set can work properily at temperatures anywhere from-40°C to+40°C.When operating at full load, the gear set temperature should not exceed 100°C.
3.What kind of gear lubricant should use?
N320 worm gear lubricant is the best.(Or Mobil SHC634 synthetic gear lubricant.)
4.How often should replace lubricating oil for the worm gear speed reducer?
During the first-time use ,change in new lubricating oil after 7 to14 days, suppose the worm gear speed reducer works no more than 8 hours every day. Affer that, replace the lubricant every 10 months.Change lubricating oil every month if your speed reducer is expected to work non-spot for a long time.
5.What are the benefits of you spiral bevel gear speed reducer over worn gear reducer?
Main benefits include higher power transmission efficency, larger torque,lower temperature increase, easier maintenance, greater design simplicity, and minimized operation noise.The spiral bevel gear set is a double-stage.This gear configuration is suitable for use on high-speed, heavy load construction elevators.
6.Can l see the specification comparison between the two types of speed reducers?
Please refer to the table below.

How to lubricate a speed reducer?

1.Gear parts are immersed in N320 lubricating oil. When the ambient temperature drops below 0°C,
use low-viscosity lube oil. lf oil level is low, fill oil to the gearbox through the filler plug
until it comes out the oil level plug.
2.During the first-time use, lubricant needs to be changed every 100 hours of operation. A fter that,
check of lubricant quality frequently. Remove impurities or degraded lubricating oil in
time. Normally speaking, lubricating oil needs to be replaced every 6 to 8 months, if the operation will be
continuous for long. Change oil every 10 months if the operation will be intemittent
and last no more than 8 hours per day.
3. Lubricating oils are identified by viscosity grades and number symbols which consist of an English
letter followed by three digits, such as symbol N320. Do not mix different number
symbols or viscosities of oils. During oil change, the worm gear needs to be heated and cleaned using
lubricant of the same number symbol.
4. If oil temperature were found to have exceeded 100°C or abnomal noise occured, stop the gear
reducer immediately for troubleshooting. The gear reducer needs to be cleaned
thoroughly once in a year. Unless parts are damaged, do not dismantle, repair or alter the gear reducer.
lf parts damage or gear teeth engagement problems were found, please contact
us soon as possible.

At the same time ,we also sold the other construction hoist spare parts, for example , construction hoist motor , construction hoist overload indicator , transmission device, Hoist Motor, roller, gear for construction hoist ,Gear rack And other products. our products are sold to Canada ,Brazil, India, Turkey, Malaysia, Italy,Spain ,United Kingdom ,American and around the world.
